Which process is used in smelting during metallurgy of copper?

Options

  1. ASelf reduction of copper
  2. BCu ₂ ~S is converted into Cu ₂ O
  3. CFeS is converted into FeO
  4. DReduction of Fe

Correct answer

C. FeS is converted into FeO

Step-by-step solution

Smelting of Cu results in slag formation and matte formation. aligned FeS + Cu ₂ O & FeO + Cu ₂ ~S FeO + SiO ₂ & FeSiO ₃ & (slag) aligned
